Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a simple sampling and dropping container used for inspection and measurement using a chemical reaction or an immune reaction.

[Prior Art] In recent years, due to the rapid progress of biotechnology, remarkable progress has been made in the progress of inspection and measurement reagents using chemical reactions or immune reactions. However, even with the reagents suitable for the new era as described above, the method of collecting the sample and the pretreatment method until the measurement of the sample are still important steps.

Conventionally, as a sample collecting container, a cap a which is attachable to and detachable from a tube a as shown in FIG. A sample is taken with a cotton swab c, inserted into a tube a, sealed with a cap b, transported, and stored.

At the time of inspection, add a diluent to the tube a to dissolve or suspend the sample, and then use a pipette or pipetter to
It measures a certain amount of sample liquid.

[Problems to be solved by the invention] The conventional container is difficult to handle because of the operation such as removing the cap at the time of inspection and measuring the sample liquid with a pipette or pipettor, and there is a risk of contamination of the surroundings. Some were lacking in speed and convenience in consideration of the safety of the measurer.

The present invention solves various drawbacks of the containers that have been used so far, and its purpose is to collect samples and perform measurement without using other instruments and without contaminating the surroundings. In addition, the safety of the operator must be taken into consideration so that it can be performed quickly and easily.

[Means for Solving the Problems] The present invention is to attach a cap to a small container made of a flexible material in a liquid-tight and detachable manner, penetrate a hollow thin tube into the cap, and a tip of the thin tube on the small container side. It is characterized in that a small hole having a diameter of about 0.2 to 0.5 mm is bored in the vicinity of the cap in addition to providing a sampling portion on the cap, the outer tip of the thin tube is sealed, and a half cut is provided in the middle part. is there.

[Operation] A sample is collected from the feces, rectum, throat, nasal cavity, etc. at the sample collecting section, sealed in a small container, transported and stored.

At the time of inspection, add an appropriate amount of sample diluent, shake to make a solution or suspension, seal with a cap, fold the thin tube at the half-cut part, invert it and press the small container with your finger, the test solution Is dripped from the cut portion through a small hole with a diameter of 0.2 to 0.5 mm and a hollow thin tube in order.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which a cap 2 made of a material such as polyethylene is liquid-tightly and detachably attached to a poly tube 1 made of a relatively soft and flexible material such as polyethylene. A hollow thin tube 3 made of, for example, Calporter EK2515 (manufactured by Eiken Co., Ltd.) is liquid-tightly penetrated through the center of the cap 2.

A cotton swab-shaped sample-collecting portion 4 is formed by winding cotton on the distal end of the thin tube 3 on the insertion side of the polytube 1, and the thin tube 3 is located in the vicinity of the cap 2 such as a position of about 5 mm from the inside of the cap 2. A small hole 5 having a diameter of about 0.2 to 0.5 mm is formed.
If the small holes are provided near the inside of the cap 2, the amount of diluent used for dissolving or suspending the sample can be reduced.

Further, a sealing portion 7 is provided at the tip of the thin tube 3 outside the cap 2 by fusing or the like, and a half cut 6 is provided in the middle of the thin tube 3 so that it can be easily broken by a finger.

In the above, the diameter of the thin tube 3 is suitable as the amount of the sample in the enzyme immunoassay (EIA) when the amount dropped from the break in the half cut 6 is 25 μl or 50 μl per drop.

Next, the method of use will be described with reference to FIG.

Remove the cap 2 from the polytube 1 and collect feces directly by the swab-shaped sampling part 4 of the thin tube 3 or rectum,
A sample is taken from a mucous membrane such as a throat or a nasal cavity, inserted into the polytube 1, sealed with a cap 2, transported, and stored. Since the outer tip of the thin tube 3 is sealed,
No contamination of the surroundings is prevented without leakage of the sample or odor.

At the time of inspection, the cap 2 is removed, a predetermined amount of the sample diluent is injected into the poly tube 1, and the poly tube 1 is sealed again with the cap 2, and the poly tube 1 is shaken to dissolve the sample adhered to the sampling portion 4. Or suspend it [Fig. 2 <a>].

Next, the outer portion of the thin tube 3 is folded at the half-cut 6 portion to break the thin tube 3 '[Fig. 2 (b)].

Then, when the poly tube 1 is inverted and pushed with a finger, the test liquid passes through the small hole 5, passes through the hollow thin tube 3, and is cut from the cut portion.
It is dropped into the well 9 of the EIA plate 8 [Fig. 2 <C>]. The dropping amount of one drop is a predetermined amount, and since the thin tube 3 acts as a dropping pipette, a pipette for collecting a dissolved or suspended diluted test liquid or a pipette operation is not required.

It should be noted that the simple sample collection and dropping container of the present invention is not limited to the above-mentioned embodiment, the small container may have a shape other than the test tube, for example, a vial shape, and the sampling part has a spatula shape instead of a cotton swab. Needless to say, various modifications can be made without departing from the scope of the present invention, such as a spatula shape.

[Advantages of the Invention] Since the present invention is configured as described above, the collected sample is dissolved or suspended in the sample diluting solution at the time of inspection, and then the half-cut portion is folded with a finger and the small container is inverted. hand,
The diameter of the hole drilled near the cap by pushing with a finger is about 0.
Since it is dropped from the small hole of 2 to 0.5 mm through the thin tube to the outside, any sample amount can be dropped on the EIA plate etc. without removing the cap.

Therefore, according to the present invention, as in the conventional case, the cap is removed,
It does not take out using other instruments such as pipettes or pipettors, does not pollute the surroundings, improves the safety of the measurer, and enables quick and easy inspection and measurement. It is possible to inspect fine particles of virus, non-viral microorganisms such as bacteria, protozoa, and parasites, protein antigens, and the like without limiting the measurement object.
